Post-training intra-basolateral complex of the amygdala infusions of clenbuterol enhance memory for conditioned place preference and increase ARC protein expression in dorsal hippocampal synaptic fractions

•Post-training activation of BLA β-adrenoceptors with clenbuterol enhances memory for an appetitive food conditioned place preference task (CPP).•Training on the CPP task upregulates dorsal hippocampal synaptic ARC protein expression.•Memory-enhancing intra-BLA administration of clenbuterol further upregulates dorsal hippocampal synaptic ARC protein expression following training on the CPP task.•De novo Dorsal hippocampal ARC protein expression is necessary for long-term memory of the CPP task.
